spice-chardev: listen to frontend guest open / close
Note the vmc_register_interface() in spice_chr_write is left in place
in case someone uses spice-chardev with a frontend which does not have
guest open / close notification.

chardev: Allow frontends to notify backends of guest open / close
Some frontends know when the guest has opened the "channel" and is actively
listening to it, for example virtio-serial. This patch adds 2 new qemu-chardev
functions which can be used by frontends to signal guest open / close, and
allows interested backends to listen to this.

spice-qemu-char: Fix flow control in client -> guest direction
In the old spice-vmc device we used to have:
last_out = virtio_serial_write(&svc->port, p, MIN(len, VMC_MAX_HOST_WRITE));
if (last_out > 0)
...
Now in the chardev backend we have:
last_out = MIN(len, VMC_MAX_HOST_WRITE);
qemu_chr_read(scd->chr, p, last_out);
if (last_out > 0) {
...
Which causes us to no longer detect if the virtio port is not ready
to receive data from us. chardev actually has a mechanism to detect this,
but it requires a separate call to qemu_chr_can_read, before calling
qemu_chr_read (which return void).
This patch uses qemu_chr_can_read to fix the flow control from client to
guest.

spice-qemu-char.c: remove intermediate buffer
RHBZ: 672191
upstream: not submitted (explained below)
virtio-serial's buffer is valid when it calls us, and we don't
access it otherwise: vmc_read is only called in response to wakeup,
or else we set datalen=0 and throttle. Then vmc_read is called back,
we return 0 (not accessing the buffer) and set the timer to unthrottle.
Also make datalen int and not ssize_t (to fit spice_chr_write signature).
This relied on the previous patch that introduces throttling, which
can't go upstream right now as explained in that patch.

spice-qemu-char.c: add throttling
RHBZ: 672191
upstream: not submitted (explained below)
Adds throttling support to spicevmc chardev. Uses a timer to avoid recursing:
1. spice-server: reds.c: read_from_vdi_port
2. qemu: spice-qemu-char.c: vmc_read
3. chr_write_unblocked
(calls virtio_serial_throttle_port(port, false))
4. qemu: virtio ...
5. qemu: spice-qemu-char.c: spice_chr_write
6. qemu: spice-qemu-char.c: wakeup (calls into spice-server)
7. spice-server: ...
8. qemu: spice-qemu-char.c: vmc_read
Instead, in vmc_read if we were throttled and we are just about to return
all the bytes we will set a timer to be triggered immediately to call
chr_write_unblocked. Then we return after 2 above, and 3 is called from the
timer callback. This also means we can later remove some ugly recursion protection
from spice-server.
The other tricky point in this patch is not returning the leftover chunk twice.
When we throttle, by definition we have data that spice server didn't consume.
It is being kept by virtio-serial, and by us. The next vmc_read callback needs
to not return it, but just do unthrottling. Then virtio will give us the remaining
chunk as usual in spice_chr_write, and we will pass it to spice server in the
next vmc_read.
This patch relies on Amit's series to expose throttling to chardev's, which
was not accepted upstream, and will not be accepted upstream until the mainloop
is reworked to use glib.

qemu-char: fix Werror=return-type

virtio-console: Enable port throttling when chardev is slow to consume data
When a chardev indicates it can't accept more data, we tell the
virtio-serial code to stop sending us any more data till we tell
otherwise. This helps in guests continuing to run normally while the vq
keeps getting full and eventually the guest stops queueing more data.
As soon as the chardev indicates it can accept more data, start pushing!

char: Throttle when host connection is down
When the host-side connection goes down, throttle the virtio-serial bus
and later unthrottle when a connection gets established. This helps
prevent any lost IO (guest->host) while the host connection was down.

char: Equip the unix/tcp backend to handle nonblocking writes
Now that the infrastructure is in place to return -EAGAIN to callers,
individual char drivers can set their update_fd_handlers() function to
set or remove an fd's write handler. This handler checks if the driver
became writable.
A generic callback routine is used for unblocking writes and letting
users of chardevs know that a driver became writable again.

char: Update send_all() to handle nonblocking chardev write requests
The send_all function is modified to return to the caller in case the
driver cannot handle any more data. It returns -EAGAIN or
WSAEWOULDBLOCK on non-Windows and Windows platforms respectively. This
is only done when the caller sets a callback function handler indicating
it's not interested in blocking till the driver has written out all the
data.
Currently there's no driver or caller that supports this. Future
commits will add such capability.

char: Add framework for a 'write unblocked' callback
The char layer can let users know that the driver will block on further
input. For users interested in not blocking, they can assign a function
pointer that will be called back when the driver becomes writable. This
patch just adds the function pointers to the CharDriverState structure,
future patches will enable the nonblocking and callback functionality.

hw/qxl-render: drop cursor locks, replace with pipe
RHBZ: 681220
upstream: http://patchwork.ozlabs.org/patch/87276/
Switching locking protection of ds->cursor_set/cursor_move to moving
every call to these functions into the iothread and using the ssd->pipe
to transfer that, adding QXL_SERVER_CURSOR_SET, QXL_SERVER_CURSOR_MOVE.
This is tested with both -vnc :0 -spice and -sdl -spice.

qxl/spice: remove qemu_mutex_{un,}lock_iothread around dispatcher
RHBZ: 681220
upstream: http://patchwork.ozlabs.org/patch/87275/
with the previous patch making sure get_command no longer needs to lock,
there is no reason to drop the qemu iothread mutex in qxl.c and in
ui/spice-display.c
The only location where the lock remains are the cursor related callbacks,
that path is currently broken. It is only triggered if running spice and sdl,
which is broken already before that.

qxl: implement get_command in vga mode without locks
RHBZ: 681220
upstream: http://patchwork.ozlabs.org/patch/87274/
This patch and the next drop the requirement to lose the global qemu
mutex during dispatcher calls. This patch enables it, the next drops
the unlock/lock pairs around dispatcher calls.
The current solution of dropping the locks is buggy:
* it allows multiple dispatcher calls from two vcpu threads, the
dispatcher doesn't handle that by design (single fd, not locked, can't
handle writes from two threads)
* it requires us to keep track of cpu_single_env, which is magic.
The solution implemented in this patch and the next (the next just
drops the locks, this patch allows that to work):
* the only operation that needed locking was qemu_create_simple_update,
* it required locking because it was called from the spice-server thread.
* do it in the iothread by reusing the existing pipe used for set_irq.
The current flow implemented is now:
spice-server thread:
qxl.c:interface_get_command (called either by polling or from wakeup)
if update!=NULL:
waiting_for_update=0
update=NULL
return update
else:
if not waiting_for_update:
waiting_for_update=1
write to pipe, which is read by iothread (main thread)
iothread:
wakeup from select,
qxl.c:pipe_read
update=qemu_create_simple_update()
wakeup spice-server thread by calling d.worker->wakeup(d.worker)

qxl/spice-display: move pipe to ssd
RHBZ: 681220
upstream: http://patchwork.ozlabs.org/patch/87270/
This moves the int pipe[2] and pthread_t main data from the
PCIQXLDevice struct to the SimpleSpiceDisplay. This will let us
reuse it in the next patch for both -spice with no -qxl usage and
for vga mode from qxl.
Also move the pipe creation function (which is effectively completely rewritten
by this patch anyways) from hw/qxl.c to ui/spice-display.c, since
spice-display will depend on it after the next patch and qemu can be build
with ui/spice-display.c in combination with no hw/qxl.c.

do not use timedwait on qemu_halt_cond
The following conditions can cause cpu_has_work(env) to become true:
- env->queued_work_first: run_on_cpu is already kicking the VCPU
- env->stop = 1: pause_all_vcpus is already kicking the VCPU
- env->stopped = 0: resume_all_vcpus is already kicking the VCPU
- vm_running = 1: vm_start is calling resume_all_vcpus
- env->halted = 0: see previous patch
- qemu_cpu_has_work(env): when it becomes true, board code should set
env->halted = 0 too.

also have qemu_thread_equal which is only used like qemu_cpu_self.

vnc: Fix stack corruption and other bitmap related bugs
Commit bc2429b9174ac2d3c56b7fd35884b0d89ec7fb02 introduced
a severe bug (stack corruption).
bitmap_clear was called with a wrong argument
which caused out-of-bound writes to the local variable width_mask.
This bug was detected with QEMU running on windows.
It also occurs with wine:
*** stack smashing detected ***: terminated
wine: Unhandled illegal instruction at address 0x6115c7 (thread 0009), starting debugger...
The bug is not windows specific!
Instead of fixing the wrong parameter value, bitmap_clear(), bitmap_set
and width_mask were removed, and bitmap_intersect() was replaced by
!bitmap_empty(). The new operation is much shorter and equivalent to
the old operations.
The declarations of the dirty bitmaps in vnc.h were also wrong for 64 bit
hosts because of a rounding effect: for these hosts, VNC_MAX_WIDTH is no
longer a multiple of (16 * BITS_PER_LONG), so the rounded value of
VNC_DIRTY_WORDS was too small.
Fix both declarations by using the macro which is designed for this
purpose.

Fix performance regression in qemu_get_ram_ptr
When the commit f471a17e9d869df3c6573f7ec02c4725676d6f3a converted the
ram_blocks structure to QLIST, it also removed the conditional check before
switching the current block at the beginning of the list.
In the common use case where ram_blocks has a few blocks with only one
frequently accessed (the main RAM), this has a performance impact as it
performs the useless list operations on each call (which are on a really
hot path).
On my machine emulation (ARM on amd64), this patch reduces the
percentage of CPU time spent in qemu_get_ram_ptr from 6.3% to 2.1% in the
profiling of a full boot.

pxa2xx_timer: separate irq for pxa27x handling
First, sysbus_init_irq shan't be called on on-stack variables. Indeed,
it only stores a passed pointer in qdev and the stored irq is later
populated, so we get a nice write-to-stack bug.
Second, irq for pxa27x should probably be handled in a more gentler way,
as we should check if we have events to raise this irq.

simpletrace: Thread-safe tracing
Trace events outside the global mutex cannot be used with the simple
trace backend since it is not thread-safe. There is no check to prevent
them being enabled so people sometimes learn this the hard way.
This patch restructures the simple trace backend with a ring buffer
suitable for multiple concurrent writers. A writeout thread empties the
trace buffer when threshold fill levels are reached. Should the
writeout thread be unable to keep up with trace generation, records will
simply be dropped.
Each time events are dropped a special record is written to the trace
file indicating how many events were dropped. The event ID is
0xfffffffffffffffe and its signature is dropped(uint32_t count).

target-arm: Implement a minimal set of cp14 debug registers
Newer ARM kernels try to probe for whether the CPU has hardware breakpoint
support. For this to work QEMU has to implement a minimal set of the cp14
debug registers. The architecture requires v7 cores to implement debug
and so there is no defined way to report its absence; however in practice
returning a zero DBGDIDR (ie with a reserved value for "debug architecture
version") should cause well-written hw debug users to do the right thing.
We also implement DBGDRAR and DBGDSAR as RAZ, indicating no memory mapped
debug components.

tcg: Add support for debugging leakage of temporaries
Add support (if CONFIG_DEBUG_TCG is defined) for debugging leakage
of temporary variables. Generally any temporaries created by
a target while it is translating an instruction should be freed
by the end of that instruction; otherwise carefully crafted
guest code could cause TCG to run out of temporaries and assert.
By calling tcg_check_temp_count() after each instruction we can
check that we are not leaking temporaries in this way.

simpletrace: Make simpletrace.py a Python module
The simpletrace.py script pretty-prints a binary trace file. Most of
the code can be reused by trace file analysis scripts, so turn it into a
module.
Here is an example script that uses the new simpletrace module:
#!/usr/bin/env python
# Print virtqueue elements that were never returned to the guest.
import simpletrace
class VirtqueueRequestTracker(simpletrace.Analyzer):
def __init__(self):
self.elems = set()
def virtqueue_pop(self, vq, elem, in_num, out_num):
self.elems.add(elem)
def virtqueue_fill(self, vq, elem, length, idx):
self.elems.remove(elem)
def end(self):
for elem in self.elems:
print hex(elem)
simpletrace.run(VirtqueueRequestTracker())
The simpletrace API is based around the Analyzer class. Users implement
an analyzer subclass and add methods for trace events they want to
process. A catchall() method is invoked for trace events which do not
have dedicated methods. Finally, there are also begin() and end()
methods like in sed that can be used to perform setup or print
statistics at the end.
A binary trace file is processed either with:
simpletrace.run(analyzer) # uses command-line args
or with:
simpletrace.process('path/to/trace-events',
'path/to/trace-file',
analyzer)

linux-user: Fix large seeks by 32 bit guest on 64 bit host
When emulating a 32 bit Linux user-mode program on a 64 bit target
we implement the llseek syscall in terms of lseek. Correct a bug
which meant we were silently casting the result of host lseek()
to a 32 bit integer as it passed through get_errno() and thus
throwing away the top half.
We also don't try to store the result back to userspace unless
the seek succeeded; this matches the kernel behaviour.

a solution.

hw/irq: Add qemu_irq_split() so one GPIO output can feed two inputs
Add a qemu_irq_split() function which allows a board to wire a single
GPIO output up to two GPIO inputs. This is needed for realview boards,
where the MMC card status is visible both in a system register and
via a PL061 GPIO module.

net: fix qemu_can_send_packet logic
If any of the clients is not ready to receive (ie it has a can_receive
callback and can_receive() returns false), we don't want to start
sending, else this client may miss/discard the packet.
I got this behaviour with the following setup :
the emulated machine is using an USB-ethernet adapter, it is connected
to the network using SLIRP and I'm dumping the traffic in a .pcap file.
As per the following command line :
-net nic,model=usb,vlan=1 -net user,vlan=1 -net dump,vlan=1,file=/tmp/pkt.pcap
Every time that two packets are coming in a row from the host, the
usb-net code will receive the first one, then returns 0 to can_receive
call since it has a 1 packet long queue. But as the dump code is always
ready to receive, qemu_can_send_packet will return true and the next
packet will discard the previous one in the usb-net code.

virtio-net: Fix lduw_p() pointer argument of wrong size
A pointer to a size_t variable was passed as the void * pointer to
lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value
this caused failure on big-endian hosts.
Avoid this issue in the future by using stw_p() instead. In general we
should use ld*_p() for loading from target memory and st*_p() for
storing to target memory anyway, not the other way around.
Also tighten up a correct use of lduw_p() when stw_p() should be used
instead in virtio_net_get_config().

target-sh4: move intr_at_halt out of cpu_halted()
All targets except SH4 have the same cpu_halted() routine, and it has
only one caller. It is therefore a good candidate for inlining.
The difference is the handling of the intr_at_halt, which is necessary
to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by
setting this variable while executing the sleep instruction, and
clearing it when the CPU has been woken-up by an interrupt, whatever the
state of SR.BL. Also rename this variable in_sleep.

This was tested with default build configuration on linux

The frequency is pre-calculated every 500ms, based on the last 10

vhost: disable on tap link down
qemu makes it possible to disable link at tap which is not communicated
to the guest but causes all packets to be dropped.
When vhost-net is enabled, vhost needs to be aware of both the virtio
link_down and the peer link_down. we switch to userspace emulation when
either is down.

net: notify peer about link status change
qemu makes it possible to disable link at tap which is not communicated
to the guest but causes all packets to be dropped.
This works for virtio userspace, as qemu stops giving it packets, but
not for virtio-net connected to vhost-net as that does not get notified
about this change.
Notify peer when this happens, which will then be used by the follow-up
patch to stop/start vhost-net.
Note: it might be a good idea to make peer link status match tap in this
case, so the guest gets an event and updates the carrier state. For now
stay bug for bug compatible with what we used to have in userspace.

the ARM encoding should have bit 28 set, not clear. This wasn't causing
any problems because we don't actually look at that bit during decode;
however it is better to do the conversion correctly to avoid problems
later if we add checks to UNDEF on SBZ/SBO bits.

qemu-lock.h: Remove non-pthreads spinlock implementations
Since configure guarantees us that we have pthreads on all hosts
except mingw (which doesn't support a USER_ONLY config), we can
and should use the pthread_mutex based implementation of spin_lock()
and spin_unlock() in all USER_ONLY cases. This means that all the
inline-native-assembly code supporting the "USER_ONLY but not USE_NPTL"
case can go away.
The not-USER_ONLY case remains as empty implementations; there is
no change in behaviour here.

e1000: verify we have buffers, upfront
The spec says: Any descriptor with a non-zero status byte has been
processed by the hardware, and is ready to be handled by the software.
Thus, once we change a descriptor status to non-zero we should
never move the head backwards and try to reuse this
descriptor from hardware.
This actually happened with a multibuffer packet
that arrives when we don't have enough buffers.
Fix by checking that we have enough buffers upfront
so we never need to discard the packet midway through.

e1000: clear EOP for multi-buffer descriptors
The e1000 spec says: if software statically allocates
buffers, and uses memory read to check for completed descriptors, it
simply has to zero the status byte in the descriptor to make it ready
for reuse by hardware. This is not a hardware requirement (moving the
hardware tail pointer is), but is necessary for performing an in–memory
scan.
Thus the guest does not have to clear the status byte. In case it
doesn't we need to clear EOP for all descriptors
except the last. While I don't know of any such guests,
it's probably a good idea to stick to the spec.

qemu i386 used to support more than 4GB of RAM through PAE, but it has

Note that simply running qemu x86_64 and emulating a 32-bit CPU is not
a solution to this problem as it is about 15% slower (it needs to
emulate 64 bit registers even if half of them are not used). On the
other hand, I haven't seen any measurable impact by switching
target_phys_bits to 64.

linux-user: correct core dump format
This patch allows to really use the core dumped by qemu with guest
architecture tools.
- it adds a missing bswap_phdr() for the program headers
of memory regions.
"objdump -x" sample:
BEFORE:
0x1000000 off 0x00200000 vaddr 0x00000400 paddr 0x00000000 align 2**21
filesz 0x00000000 memsz 0x00100000 flags ---
0x1000000 off 0x00200000 vaddr 0x00100400 paddr 0x00000000 align 2**21
filesz 0x00000000 memsz 0x00080000 flags --- 6000000
AFTER:
LOAD off 0x00002000 vaddr 0x00040000 paddr 0x00000000 align 2**13
filesz 0x00000000 memsz 0x00001000 flags ---

filesz 0x00000000 memsz 0x00000800 flags rw-
- it doesn't pad the note size to sizeof(int32_t).
On m68k the NT_PRSTATUS note size is 154 and
must not be rounded up to 156, because this value is checked by
objdump and gdb.
"gdb" symptoms:
"warning: Couldn't find general-purpose registers in core file."

linux-user: Define target alignment size
Datatype alignment can be found using following application:
int main(void)
{
printf("alignof(short) %ld\n", __alignof__(short));
printf("alignof(int) %ld\n", __alignof__(int));
printf("alignof(long) %ld\n", __alignof__(long));
printf("alignof(long long) %ld\n", __alignof__(long long));
}
This patch includes following alignments:
i386
alignof(short) 2
alignof(int) 4
alignof(long) 4
alignof(long long) 8
x86_64
alignof(short) 2
alignof(int) 4
alignof(long) 8
alignof(long long) 8

linux-user: Support the epoll syscalls
Support the epoll family of syscalls: epoll_create(), epoll_create1(),
epoll_ctl(), epoll_wait() and epoll_pwait(). Note that epoll_create1()
and epoll_pwait() are later additions, so we have to test separately
in configure for their presence.

We no longer do, so there is no need for those workarounds. Even worse

qemu-kvm: Clean up IOAPIC after upstream merge
Drop base_address from the vmstate, upstream decided against managing it

kvm: make tsc stable over migration and machine start
If the machine is stopped, we should not record two different tsc values
upon a save operation. The same problem happens with kvmclock.
But kvmclock is taking a different diretion, being now seen as a separate
device. Since this is unlikely to happen with the tsc, I am taking the
approach here of simply registering a handler for state change, and
using a per-CPUState variable that prevents double updates for the TSC.

kvm: Separate TCG from KVM cpu execution
Mixing up TCG bits with KVM already led to problems around eflags
emulation on x86. Moreover, quite some code that TCG requires on cpu
enty/exit is useless for KVM. So dispatch between tcg_cpu_exec and
kvm_cpu_exec as early as possible.
The core logic of cpu_halted from cpu_exec is added to
kvm_arch_process_irqchip_events. Moving away from cpu_exec makes
exception_index meaningless for KVM, we can simply pass the exit reason
directly (only "EXCP_DEBUG vs. rest" is relevant).

Move debug exception handling out of cpu_exec
To prepare splitting up KVM and TCG CPU entry/exit, move the debug
exception into cpus.c and invoke cpu_handle_debug_exception on return
from qemu_cpu_exec.
This also allows to clean up the debug request signaling: We can assign
the job of informing main-loop to qemu_system_debug_request and stop the
calling cpu directly in cpu_handle_debug_exception. That means a debug
stop will now only be signaled via debug_requested and not additionally
via vmstop_requested.

kvm: Unconditionally reenter kernel after IO exits
KVM requires to reenter the kernel after IO exits in order to complete
instruction emulation. Failing to do so will leave the kernel state
inconsistently behind. To ensure that we will get back ASAP, we issue a
self-signal that will cause KVM_RUN to return once the pending
operations are completed.
We can move kvm_arch_process_irqchip_events out of the inner VCPU loop.
The only state that mattered at its old place was a pending INIT
request. Catch it in kvm_arch_pre_run and also trigger a self-signal to
process the request on next kvm_cpu_exec.
This patch also fixes the missing exit_request check in kvm_cpu_exec in
the CONFIG_IOTHREAD case.

kvm: Fix race between timer signals and vcpu entry under !IOTHREAD
Found by Stefan Hajnoczi: There is a race in kvm_cpu_exec between
checking for exit_request on vcpu entry and timer signals arriving
before KVM starts to catch them. Plug it by blocking both timer related
signals also on !CONFIG_IOTHREAD and process those via signalfd.
As this fix depends on real signalfd support (otherwise the timer
signals only kick the compat helper thread, and the main thread hangs),
we need to detect the invalid constellation and abort configure.

Date: Tue Feb 1 22:15:43 2011 +0100
Stop current VCPU on synchronous reset requests
If some I/O operation ends up calling qemu_system_reset_request in VCPU
context, we record this and inform the io-thread, but we do not
terminate the VCPU loop. This can lead to fairly unexpected behavior if
the triggering reset operation is supposed to work synchronously.
Fix this for TCG (when run in deterministic I/O mode) by setting the
VCPU on stop and issuing a cpu_exit. KVM requires some more work on its
VCPU loop.

Flatten the main loop
First of all, vm_can_run is a misnomer, it actually means "no request
pending". Moreover, there is no need to check all pending requests
twice, the first time via the inner loop check and then again when
actually processing the requests. We can simply remove the inner loop
and do the checks directly.

Prevent abortion on multiple VCPU kicks
If we call qemu_cpu_kick more than once before the target was able to
process the signal, pthread_kill will fail, and qemu will abort. Prevent
this by avoiding the redundant signal.
This logic can be found in qemu-kvm as well.

Leave inner main_loop faster on pending requests
If there is any pending request that requires us to leave the inner loop
if main_loop, makes sure we do this as soon as possible by enforcing
non-blocking IO processing.
At this change, move variable definitions out of the inner loop to
improve readability.

Trigger exit from cpu_exec_all on pending IO events
Except for timer events, we currently do not leave the loop over all
VCPUs if an IO event was filed. That may cause unexpected IO latencies
under !CONFIG_IOTHREAD in SMP scenarios. Fix it by setting the global
exit_request which breaks the loop.

qcow2: Fix order in L2 table COW
When copying L2 tables (this happens only with internal snapshots), the order
wasn't completely safe, so that after a crash you could end up with a L2 table
that has too low refcount, possibly leading to corruption in the long run.
This patch puts the operations in the right order: First allocate the new
L2 table and replace the reference, and only then decrease the refcount of the
old table.

QCOW2: bug fix - read base image beyond its size
This patch fixes the following bug in QCOW2. For a QCOW2 image that is larger
than its base image, when handling a read request straddling over the end of the
base image, the QCOW2 driver attempts to read beyond the end of the base image
and the request would fail.
This bug was found by Fast Virtual Disk (FVD)'s fully automated testing tool.
The following test triggered the bug.

device-assignment: Properly terminate vmsd.fields

recent qemu fixes to the no_migrate flag should ensure this, but let's
avoid setting the wrong precedent.
